*1 The throw ratio is based on the value during projection with the projected image size of 3.81 m (150").
*2 When the Fixed-focus Lens (Model No.: ET-D75LE95, ET-D75LE90) is used, the projection relation between the screen and the projector differs
from that of other lenses. Refer to "Fixed-focus Lens (Model No.: ET-D75LE95, ET-D75LE90)" (x page 38) for details.
